从JavaScript函数返回多个变量?

时间:2022-12-28 16:43:20

In python, to return multiple variables, I can do --

在python中,要返回多个变量,我可以做 -

def function_one(i):
    return int(i), int(i) * 2

value, duble_value = function_one(1)

How would I achieve this same result using javascript if functions may only return a single return value? (I assume using an array?)

如果函数只返回一个返回值,我将如何使用javascript实现相同的结果? (我假设使用数组?)

You need to either use an array or an object.

您需要使用数组或对象。

For example:

例如:

function test() {
    return {foo: "bar", baz: "bof"};
}

function test2() {
    return ["bar", "bof"];
}

var data = test();
foo = data.foo;
baz = data.baz;

data = test2();
foo = data[0];
baz = data[1];

function foo(){
    return ["something","something else","something more","something further"];
}

let [a,b,c,d] = foo();
